Listers now supplies the full range of Sheerline products, including the Prestige window and S1 Sheerline lantern. Sheerline from Garnalex is a modern aluminium window and door system.
The latest development from the aluminium systems company is a powder coating facility, which aims to control quality and shorten lead times on ex-stock coloured profile, bringing them in line with PVC-U alternatives. For example, black, white and grey will be supplied by Listers on a two-week lead time, with a further nine on-trend colours available in four weeks.
Roy Frost, Listers’managing director , said: “After meeting with the engineers right at the start of the Sheerline journey, I could see exactly what they were trying to do in aluminium. It is a real breath of fresh air: an aluminium system designed by PVC system designers.
”Part L of the building regulations includes a reduction in U-values to 1.4W/m²K for bi-fold doors in refurbishment projects. I know that many of the systems on the market struggle to meet this without expensive glazing specifications. Sheerline on the other hand is Part L-compliant as standard.”
Using the patented Thermlock multi-chamber design, Sheerline Prestige windows can achieve U-values as low as 1.3W/m²k with a double glazed unit, 0.9W/m²k with a triple, and can accommodate glazing depths of between 28mm and 44mm. It has also been designed to reduce its impact on the environment, sourcing aluminium from Wales, extruding in the UK and recycling all aluminium waste. Sheerline also achieves the PAS24 security standard and has full Secured by Design accreditation.
